Abstract
A starter is provided including a housing defining a fluid passageway with an inlet and an outlet. A turbine rotor is supported in the housing and includes blades arranged in the passageway between the inlet and the outlet. The rotor is movable within the passageway at a speed with a fluid exiting the blade toward the outlet. A spoiler is arranged in the passageway between the rotor and the outlet. The spoiler deflects the fluid exiting the blade and reduces the rotor speed. Preferably, the present invention spoiler is utilized to reduce the maximum speed at the no-load condition. The angle, number, position, and other characteristics of the spoiler may be tailored for the particular turbine and a particular speed for which it is desirable to reduce.
